摘要
A phosphor consisting of a solid solution of a complex oxide of alkaline earth metals, aluminum and silicon, which contains oxides of the alkaline earth metals (Ca, Sr and Ba), aluminum and silicon as a host material, which is activated by divalent europium (Eu2+), shows a bright luminescence spectrum in a wavelength region from near ultraviolet to bluish white, which depends upon the composition of the host material, through an excitation by ultraviolet rays or electron beams. The phosphor is utilized as a blue component for a fluorescent discharge lamp for copying, a flying spot tube, a storage tube or a Braun tube.
